水產養殖業使用高能量飼料是目前流行的趨勢,但提高飼料非蛋白質能量的供應(特別是由脂質提供)常伴隨著魚體脂肪含量的增加。高能量的攝取也會影響養殖魚蝦的品質,因為體脂肪蓄積的部位、含量與組成將影響其營養價值、風味、轉化率以及貯存的安定性。其中肉鹼因具有降低禽畜體脂、提高肌肉品質以及多項生理功能,被視為類維生素物質而廣泛添加於畜產飼料中,本試驗擬研究飼料中添加肉鹼對銀鱸成長與體脂質分佈之影響,以利用飼料添加的方式達到改變魚肉成分組成之目的,進而增進淡水魚對人類的營養價值。

研究報告摘要(英)


The use of low fish meal and high energy diets is a current practice in the aquacultureindustry, as these diets have been considered beneficial for economic and nutritionalreasons. However, such diet with high levels of alternative plan proteins and/or nonproteinenergy supply (particularly through fats) is generally associated with an increasein whole-body lipids. Increasing awareness exists of the effects of such high caloric intakeon the quality of fish products as human food, because the localization, quantitativeimportance and composition of body fat deposits may affect their dietetic value,organoleptic properties, transformation yield and storage stability. The ami of this studyis conducted to elucidate the effect of dietary carnitine on the growth performance andbody lipid distribution of silver perch.
